[0010] The feature is that the cover structure comprises:

[0011] cover body;

[0012] The sliding cover is located above the sealing ring and is configured to be arranged on the cover body to slide back and forth along a preset direction of the cover body under an external driving force;

[0013] An extrusion piece is disposed between the sliding cover and the sealing ring and can move up and down;

[0014] The sliding cover is connected with the extrusion piece, and the sliding of the sliding cover can drive the extrusion piece to move up and down. The downward movement of the extrusion piece can squeeze the periphery of the sealing ring, so that the sealing ring is pressed tightly against the inner wall of the storage cavity.

[0015] Improved, in the sealed can with a sliding sealing structure, the cover structure further comprises:

[0016] A slide rail is arranged on the slide cover, and the slide rail has a track high point, a track low point, and an inclined track body respectively connecting the track high point and the track low point;

[0017] a sliding fitting portion disposed on the extrusion member, the sliding fitting portion being configured to be slidably disposed within the slide rail to slide back and forth along a formation direction of the slide rail;

[0018] Among them, when the sliding cover slides along a preset direction and the sliding fitting part moves from a high point of the track to a low point of the track along the direction of the slide rail, the sliding fitting part drives the extrusion part to move downward to extrude the sealing ring to produce an expansion deformation toward the inner wall of the storage cavity; when the sliding cover slides in the opposite direction of the preset direction and the sliding fitting part moves from a low point of the track to a high point of the track along the direction of the slide rail, the sliding fitting part drives the extrusion part to move up in a direction away from the sealing ring.

[0019] Furthermore, in the sealed can with a sliding sealing structure, a bottom plate is fixed on the cover body, the sealing ring is mounted on the bottom plate, the extrusion piece is located above the bottom plate, and a notch is formed on the bottom plate to cooperate with the upward and downward movement of the sliding fitting part.

[0020] Further improvement, in the sealed tank with sliding sealing structure, the sealing ring has:

[0021] Sealing ring body;

[0022] The elastic side wall is formed along the circumference of the sealing ring body and extends outwardly toward the upper side of the sealing ring body to form a first cavity with the sealing ring body. The bottom plate is arranged in the first cavity.

[0023] Improved, in the sealed can with a sliding sealing structure, the slide rail is formed on the sliding cover.

[0024] As an improvement, in the sealed can with a sliding sealing structure, the sliding cover has a force-bearing portion that bears the external driving force.

[0025] As a further improvement, in the sealed can with a sliding sealing structure, an opening and a track groove are formed on the cover body, and the sliding cover is arranged at the opening and slides back and forth along the track groove.

[0026] As a further improvement, in the sealed can with a sliding sealing structure, the cover body, the sealing ring, the sliding cover, the extrusion piece and the bottom plate are assembled together in a detachable manner.

[0027] Compared with the prior art, the advantages of the utility model are:

[0028] Firstly, the sealed can in the utility model is improved on the basis of the existing can body, cover structure and sealing ring, and the cover structure is a sliding structure. The cover structure can slide under an external driving force to make the sealing ring close to or away from the inner wall of the container cavity of the can body, so as to achieve the sealing of the can body by the cover structure or release the sealing of the can body by reverse sliding. In this way, the user only needs to apply a small external driving force (i.e., thrust or return force) to achieve the sliding of the sliding cover on the cover structure, achieve or release the sealing of the can body by the sealing ring, and it is more convenient for the user to achieve the sealing operation of the can body of the sealed can through simple and easy operation. Compared with the traditional sealing method of sealing the can body by moving the can cover up and down, the sealing method of the sliding cover structure adopted in the utility model is simpler and more convenient.

[0029] Secondly, in the sealed can of the utility model, the sealing ring is arranged on the cover structure to fit with the inner wall of the can body's content cavity. During the process of sealing or opening the can body, the relative position of the sealing ring in the can body's content cavity remains unchanged, and there is no need to move up and down with the cover structure. This avoids the shaking of the sealing ring due to the up and down movement, enhances the sealing effect of the sealing ring on the can body's content cavity, and can also avoid friction between the sealing ring and the inner wall of the content cavity due to relative up and down movement. In this way, the service life of the sealing ring can be extended.

[0030] Finally, by assembling the cover body, sealing ring, sliding cover, extrusion part and bottom plate on the cover structure together in a detachable manner, each component can be easily disassembled and separated for individual cleaning, ensuring the overall cleanliness of the cover structure.

The can body 1 has a container cavity 10 with an upper opening; the cover structure is used to cooperate with the can body 1 to cover the upper opening of the container cavity 10 of the can body; the sealing ring 3 is provided on the cover structure and is configured to fit with the inner wall of the container cavity 10 of the can body 1. The cover structure in this embodiment includes a cover body 2, a sliding cover 4 and an extrusion member 5. The sliding cover 4 is located above the sealing ring 3 and is configured to be set on the cover body 2 to slide back and forth along the preset direction of the cover body 2 under an external driving force, for example, the preset direction here is along the horizontal direction (length direction) or the longitudinal direction (width direction) of the cover body; the extrusion member 5 is set between the sliding cover 4 and the sealing ring 3 and can move up and down; wherein, the sliding cover 4 is connected with the extrusion member 5, the sliding of the sliding cover 4 can drive the extrusion member 5 to move up and down, and the downward movement of the extrusion member 5 can squeeze the periphery of the sealing ring 3, so that the sealing ring 3 is pressed against the inner wall of the container cavity 10. In this way, under the external driving force, the sealing ring 3 is made to be in close contact with the inner wall of the container cavity 10 of the tank body 1 by sliding, and the sealing of the tank body by the cover structure can be realized when the sealing ring 3 is in close contact with the inner wall of the container cavity 10; and when the sealing ring 3 is away from the inner wall of the container cavity 10 of the tank body 1, the sealing of the tank body by the cover structure is released.

[0045] As a way to realize that the sliding cover drives the extrusion member to move up and down by sliding, see Figures 4 to 6 As shown, the cover structure of this embodiment includes a slide rail 6 and a sliding fitting portion 7. The slide rail 6 is arranged on the sliding cover 4, and the slide rail 6 has a track high point 61, a track low point 62, and an inclined track body 60 respectively connecting the track high point 61 and the track low point 62; the extrusion member 5 is arranged between the sliding cover 4 and the sealing ring 3; the sliding fitting portion 7 is arranged on the extrusion member 5, and the sliding fitting portion 7 is configured to be slidably arranged in the slide rail 6 to slide back and forth along the formation direction of the slide rail 6; wherein the sliding cover 4 slides along a preset direction When the sliding fitting part 7 moves from the track high point 61 to the track low point 62 along the direction of the slide rail 6, the sliding fitting part 7 drives the extrusion part 5 to move downward to extrude the sealing ring 3 to produce an expansion deformation toward the inner wall of the storage chamber 10, so that the sealing ring after the expansion deformation is tightly attached to the inner wall of the storage chamber to seal the tank body; when the sliding cover 4 slides in a preset direction and the sliding fitting part 7 moves from the track low point 62 to the track high point 61 along the direction of the slide rail 6, the sliding fitting part 7 drives the extrusion part 5 to move up in a direction away from the sealing ring 3.

[0046] In this embodiment, the sliding fitting portion 7 can be provided on the extrusion member 5 as an independent component, or the sliding fitting portion 7 can be formed on the extrusion member 5. According to actual needs, the extrusion member 5 here is generally ring-shaped as a whole, and has a plurality of symmetrically distributed sliding fitting portions 7 on the extrusion member 5.

[0047] In order to ensure that the extrusion piece stably squeezes the sealing ring when the sliding cover slides, as an improvement measure, a bottom plate 8 is fixed to the cover body 2 of this embodiment, the sealing ring 3 is installed on the bottom plate 8, the extrusion piece 5 is located above the bottom plate 8, and a notch 80 is formed on the bottom plate 8 to cooperate with the upward and downward movement of the sliding fitting part 7. For example, a plurality of vertical side walls 81 extending upward are formed on the bottom plate 8, and the notches 80 are formed on the corresponding vertical side walls 81.

That is, the slide rails 6 are formed on the symmetrical left and right walls of the sliding cover. In this way, it can be ensured that when the sliding cover slides along the cover body, the cover structure can seal or unseal the can body 1 more stably and smoothly.

[0050] Furthermore, an opening 20 and a track groove 21 are formed on the cover body 2 , and the sliding cover 4 is disposed at the opening 20 and slides back and forth along the track groove 21 .

[0051] See also Figure 5 As shown, the sealing ring 3 of this embodiment has a sealing ring body 31 and an elastic side wall 32, the side wall 32 is formed along the circumference of the sealing ring body 31 and extends outwardly toward the top of the sealing ring body 31 to form a first cavity 30 with the sealing ring body 31, and the bottom plate 8 is arranged in the first cavity 30.

[0052] As a way of disposing the bottom plate on the sealing ring, the bottom plate 8 is fixed on the sealing ring body 31 of the sealing ring 3 by snapping.

[0053] In order to facilitate the external driving force applied to the sliding cover, see Figures 1 to 6 As shown, the sliding cover 4 of this embodiment has a force-bearing portion 41 for bearing the external driving force. For example, the force-bearing portion 41 here is a groove for convenient hand operation.

[0054] Of course, according to actual cleaning needs, in this embodiment, the cover body 2, the sealing ring 3, the sliding cover 4, the extrusion piece 5 and the bottom plate 8 on the cover structure are assembled together in a detachable manner, so that each component can be easily disassembled and separated for separate cleaning to ensure the overall cleanliness of the cover structure. That is, among the cover body 2, the sealing ring 3, the sliding cover 4, the extrusion piece 5 and the bottom plate 8, two components that are connected to each other are connected in a detachable manner.

[0055] The following combination Figures 1 to 12 , the principle of the sealed tank with a sliding sealing structure in this embodiment is explained:

[0056] When a cover structure is required to seal the tank body of the sealed tank, refer to Figures 7 to 9 As shown, manually apply force to the force-bearing part on the sliding cover from the right side of the sliding cover toward the left side of the sliding cover (see Figure 7 The sliding cover slides along the cover body, so that the sliding fitting part moves from the high point of the track to the low point of the track along the direction of the slide rail, and the sliding fitting part drives the extrusion part to move downward to squeeze the sealing ring to generate expansion deformation toward the inner wall of the storage cavity, so that the sealing ring after expansion deformation is closely attached to the inner wall of the storage cavity, thereby sealing the tank body;

[0057] When it is necessary to release the seal of the can body of the sealed can by the cover structure, refer to Figures 10-12 As shown, manually apply force to the force-bearing part on the sliding cover from the left side of the sliding cover toward the right side of the sliding cover (see Fig.10 The sliding cover slides in the opposite direction along the cover body, so that the sliding fitting part moves from the bottom point of the track to the top point of the track along the direction of the slide rail, and the sliding fitting part drives the extrusion part to move upward to make the extrusion part away from the sealing ring, so that the extrusion part no longer squeezes the sealing ring, and the sealing ring returns to its original state without expansion deformation, so that the sealing ring no longer clings to the inner wall of the storage cavity, thereby releasing the sealing of the sealed can body by the cover body structure.

[0058] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
